Question

You are developing a mobile app for employees to scan and store their expenses while traveling. Which type of computer vision should you use?

A. Optical Character Recognition.
B. Object detection.
C. Facial detection.
D. Image classification.

Answer

A. Optical Character Recognition.

A. Optical Character Recognition (OCR) is the correct type of computer vision to use for developing a mobile app that scans and stores employee travel expenses.

Explanation

OCR is a computer vision technique that enables software to detect and extract text from images. In the context of an expense scanning app, OCR would allow the app to:

1. Recognize and digitize printed or handwritten text on receipts, invoices, and other expense documents that employees photograph with their mobile device camera.
2. Extract relevant information such as vendor names, dates, amounts, expense categories, etc. This data can then be automatically populated into expense reports.
3. Store the extracted text along with the original document images for recordkeeping, processing, and reimbursement.

The other computer vision options are not suitable for this use case:

• Object detection identifies instances of objects in images but does not extract text.
• Facial detection locates and identifies human faces, which is not relevant for expense documents.
• Image classification categorizes images into predefined classes, but does not extract textual details needed for expenses.

So in summary, OCR is the best computer vision technology to enable a mobile app to intelligently scan, recognize, extract and store expense information from images of documents captured by employees. It eliminates manual data entry, improves efficiency and accuracy in expense reporting.
